 |
|
Hello,
I was trying to get audio working on my Gentoo Linux installation. I installed alsa-utils and pavucontrol. Pavucontrol can't gen any hardware audio devices and commands like , | Code: | | cat /proc/asound/cards |
or [/code]return that there is no sound cards on my system. I have followed official gentoo wiki articles for PulseAudio and for ALSA
Already tried using solutions for similar problems, but I had no luck.
My motherboard is Gigabyte Z390 D
Processor: i5 9400F
Graphics card: Nvidia Geforce GTX 1650
Here is my kernel .config
Output of
| Code: | lspci |grep -i audio

I am still pretty new to kernel configuration and gentoo.
Thank you for your attention! |

cygan,
Welcome to Gentoo Forums !
I have also an Intel CPU with a Gigabyte mainboard. I have seen this in your dmesg:
| Code: | [ 3.473924] snd_hda_intel 0000:01:00.1: Disabling MSI
[ 3.488050] snd_hda_intel 0000:01:00.1: Cannot probe codecs, giving up |
... BUT ... you have all codecs enabled:
| Code: | CONFIG_SND_HDA_CODEC_REALTEK=y
CONFIG_SND_HDA_CODEC_VIA=y
CONFIG_SND_HDA_CODEC_HDMI=y
CONFIG_SND_HDA_CODEC_SI3054=y
CONFIG_SND_HDA_GENERIC=y |
(You will need only REALTEC, HDMI and GENERIC)
This is not necessary:
| Code: | | CONFIG_SND_INTEL8X0=y |
... Now, the question is why you kernel cannot probe it ? I see two big differences to my kernel .config:
| Code: | CONFIG_INTEL_IOMMU=y
# CONFIG_INTEL_IOMMU_SVM is not set
# CONFIG_INTEL_IOMMU_DEFAULT_ON is not set
CONFIG_INTEL_IOMMU_FLOPPY_WA=y
CONFIG_INTEL_IOMMU_SCALABLE_MODE_DEFAULT_ON=y
# CONFIG_IRQ_REMAP is not set |
IOMMU is important ... please enable ALL
You have disabled:
| Code: | # CPU Frequency scaling
#
# CONFIG_CPU_FREQ is not set
# end of CPU Frequency scaling |
That is not good. See mine:
| Code: | #
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_GOV_ATTR_SET=y
CONFIG_CPU_FREQ_STAT=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL=y
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_GOV_POWERSAVE is not set
# CONFIG_CPU_FREQ_GOV_USERSPACE is not set
# CONFIG_CPU_FREQ_GOV_ONDEMAND is not set
# CONFIG_CPU_FREQ_GOV_CONSERVATIVE is not set
CONFIG_CPU_FREQ_GOV_SCHEDUTIL=y
#
# CPU frequency scaling drivers
#
CONFIG_X86_INTEL_PSTATE=y
# CONFIG_X86_PCC_CPUFREQ is not set
# CONFIG_X86_AMD_PSTATE is not set
# CONFIG_X86_AMD_PSTATE_UT is not set
# CONFIG_X86_ACPI_CPUFREQ is not set
# CONFIG_X86_SPEEDSTEP_CENTRINO is not set
# CONFIG_X86_P4_CLOCKMOD is not set |
Your i5-9400F has no integrated GPU ... so please disable all i915 modules.
If this doesnt help I recommend:
1. Boot an UbuntuLiveCD and do:
a) "lsmod" (notice all modules)
b) "lspci -k" (notice all kernel driver in use)
2. Give us these infos + your actual (=with above changes) kernel .config and a complete "dmesg" from gentoo boot.
Please use for big files "wgetpaste" => https://wiki.gentoo.org/wiki/Wgetpaste |
